Half- and quarter-metals in rhombohedral trilayer graphene

Ferromagnetism is most common in transition metal compounds where electrons occupy highly localized d orbitals. However, ferromagnetic order may also arise in low-density two-dimensional electron systems 1 – 5 . Here we show that gate-tuned van Hove singularities in rhombohedral trilayer graphene 6...
